1964 GM A-Body Handling Kit- Stage 4, 1" Lowering Spring ABF407-64-1-B

Who says you can't have it all UMI's Stage 4 kit transforms your A-body into a handling machine with the adjustability to perform well at the strip or haul your family comfortably - to the autocross. If drag racing is more your style, a few minor changes at initial purchase (or down the road) will have you launching with the best of them, then canyon carving on the way home! Up front we start with UMI's proven upper and lower tubular a-arms loaded with ┬╜" taller upper ball joints. The upper a-arms increase caster, without additional shims, for a precise steering feel and straight line stability. The lower a-arms are loaded with UMI-built Delrin bushings for smooth motion and precise steering. Viking's front hybrid coilovers with double adjustable shocks allows ride height, compression and rebound adjustment. The ride height adjustment is accomplished with the included spanner wrenches and thrust washers. The compression and rebound adjusters are clicked by hand (no tools!) and feature a total of 361 possible valving combinations. The front is completed by UMI's 1.250" CrMo handling sway bar. Out back we stiffen the chassis with adjustable tubular frame braces which stabilize the Poly/Roto combo lower trailing arms and fully adjustable Roto-Joint upper control arms. 1" or 2" rear lowering springs are controlled by Viking's double adjustable rear shocks, once again featuring 361 possible combinations. Rounding out the rear is our three way adjustable 1" tubular Pro-Tour sway bar. This handling sway bar attaches to the axle housing and also to the rear crossmember for a bind-free system (requires drilling four 3/8" holes). As always, this kit features UMI's quality red or black powder coat and premium hardware. All UMI components are manufactured with pride in Philipsburg, PA - USA.
